separate build.h and config.h usage (now possible because newconfig is gone) 

Signed-off-by: Stefan Reinauer <stepan@coresystems.de>
Acked-by: Patrick Georgi <patrick.georgi@coresystems.de>

This patch is slightly reworked to include a necessary romcc change that allows
more than one -include specified on the command line, and gets rid of the
explicit build.h dependencies of all files. (The files do keep an explicit
config.h dependency though)
